VE3008 CE3008 KJ2005X1-MQ1 12P6381X022 is initialized only once for all objects (not just static objects), and because static variables have a “memory” function, they are not destroyed after initialization and are saved in the memory area, so they will not be initialized again.

The lifecycle of variables stored in static areas is generally relatively long, and they are usually “living and dying together” with the entire source program, so they only need to be initialized once.

VE3008 CE3008 KJ2005X1-MQ1 12P6381X022 is a type modifier. It is designed to modify variables that are accessed and modified by different threads. If there were no volatile, it would basically result in either inability to write multi-threaded programs or the compiler losing a lot of optimization opportunities.

If there is no volatile keyword, the compiler may optimize reading and storage, and may temporarily use the value in the register. If this variable is updated by another program, inconsistency will occur.
